Otorhinolaryngology litigations in Japan.

Abstract

The purposeof this study was to examine the malpractice litigations pertaining to otorhinolaryngology in Japan. A retrospective review was undertaken of cases tried in the Japanese civil court system during the 26-year period from 1990 to 2015 as identified in a computerized legal database. Data including patient demographics, disease, chief allegations, court's decisions, and the year decision was made were collected and analyzed. Patients' chief allegations were assigned to one of the five categories: delayed diagnosis, complication during diagnostic procedure, inappropriate treatment, complication during treatment procedure, or lack of informed consent. Thirty-one malpractice litigations were identified. Eight (26%) malpractice litigations pertained to tumors, 1 (3%) to a tumor-like lesion, 14 (45%) to inflammation, and 8 (26%) to others. Among the patients' chief allegations, inappropriate treatment and complication during treatment procedure were the most frequent [11 (36%) for each], followed by delayed diagnosis [6 (19%)], complication during diagnostic procedure [2 (6%)], and lack of informed consent [1 (3%)]. These data may aid in the design of risk-prevention strategies to be used by otorhinolaryngologists.
